A rig hand removes drill pipe from a natural gas well owned by EQT Corp. at a hydraulic fracturing site located atop the Marcellus shale rock formation in Washington Township, Pennsylvania, U.S. Output from shale deposits including the Marcellus surged 10-fold between 2005 and 2013, to account for a third of the country's gas production, government data show. The increase in production is bringing development to an economically depressed region that lies atop the Marcellus shale, a rock formation that produces more natural gas than Saudi Arabia.
